Its weight is also lower than usual - 38,47 grams. It is usual to find 5 kopeks coins thicknesses and weights so different? Kind regards, Miguel Report this Post to the Staff

I have a 1794 5 kopeks, a nice grade specimen with weight 51.31 grams. Report this Post to the Staff
january1may Pillar of the Community Russian Federation 5174 Posts	Posted 01/11/2015 12:31 pm These 5 kopek coins vary ludicrously in weight (the heaviest examples are about twice as heavy as the lightest ones). I don't recall what the "standard" is, actually (though it's probably around 51 grams), but your coin seems to be well within typical variance (if a bit on the low side).

Reason being why there is such a variance is because these coins were only weighted in lots of 1000 coins unlike silver and gold coins where each coin was individually weighted and tested. Therefore if a lot of 1000 copper coins was within tolerance level, and if there is a sufficient mix of low and high weighted coins were in the lot - they essentially pass through quality assurance. That said, the normal weight of these coins should be around 50 grams and it's harder to find coins on the extreme end.
